Performance optimization of integrated network control schemes in packet-switched networks

Integrated schemes of routing, flow control, and congestion control in packet-switched networks are investigated for performance optimization. After the control parameters and objective function are introduced, an efficient method is derived to compute the gradient vector and Hessian matrix of such an objective function. The method, used with a general nonlinear programming strategy, solves this nonlinear optimization problem. Several examples which showed efficient and stable behavior were investigated. The results obtained by the proposed method are compared with exact values and are shown to be accurate
